Application filed July 23, 1925. Serial No. 45,489.

My invention relates to a new and useful improvement in a door frame,particularly adaptable for framing a door opening intended for use inicing refrigerators, and the like. It isan object of the presentinvention, to provide a metallic door frame, which will be simple instructure, economical of manufacture, highly efiicient. in use, andeasily. and quickly assembled, mounted and secured in the door opening,with which ity is intended tobe used.

Another object of the present invention is the provision of a metallicdoor frame of this class, which may be provided with a shelf and asecondary door, so as to provide a. chamber above the opening of thedoor, ordinarily used for icing a refrigerator.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of partshereinafter described and claimed.

The invention will be best understood from a reference to theaccompanying drawings, which form a part of this specification and inwhich Fig. 1 is a vertical central sectional view of the invention,

Fig. 2 is a fragmentary enlarged view of the section shown in Fig. 1,

Fig. 3 is a side elevational view of the invention, showing an outsidedoor attached.

Fig. 4 is a sectional view taken on substantially 44 of Fig. 3.

As shown in the drawings, the metallic casing or frame, which is adaptedto frame the door opening 17, formed in the wall 10, comprises a pair ofinterlocking sections, one of which is adapted for insertion into theopening from one side of the wall, and the other from the opposite sideof the wall, the inwardly projecting ends of the two sectionsinterlocking and being secured together in any desirable manner. One ofthe sections comprises the inwardly projecting main body portion 7,having the angularly turned portion 8 terminating in a further angularlyturned port-ion 9, which is adapted to engage one face of the wall 10and which extends at right angles to the main body 7 The other sectioncomprises a main body 11 having a similar pair of angularly turnedportions 12 and 13. The inner end of the body 11 has the doubled overportion 14, which is, in turn, doubled upon itself, to provide theportion 15, which is spaced from the portion 14, to form a channel inwhich the inner end of the main body 7 engages. As shown in thedrawings, the frame is secured to the wall 10, and the inner ends of thetwo sections are secured in assembled relation by nails 16 driven intothe wall 10. Swingably mounted on the outer section 11 is a door'24c,upon the opening of which access may be had to the rear door of therefrigerator 23, the structure of this rear door of the refrigerator 23not being shown,-inasmuch as it forms no part of the present invention.

When the frame, constructed as described, is mounted in the opening 17,a metallic frame is provided which serves to protect the wall andprevent its being marred when the refrigerator is being iced. By havingthe ends 12 and 13 formed in the manner shown, when the two sections arebeing mounted in the opening 17, these sections may be pressed inwardlytoward each other,

so as to exert strain upon the angularly turned portions 8 and 9 andangularly turned portions 12 and 13, so that the portions 9and 13 willbe bearing against the I opposite faces of the wall 10 in response tothe tension exerted on account ofthe resiliency of the sheet metal, fromwhich the frame is constructed, this connection being sufficiently closeto prevent leakage of water into the opening or onto the portions 7 and11.

It will be noted that the two sections are COIlStIUCtGQ exactly alike,saving the doubled-over portion of the inner edge of one of thesections. This doubled-over portion may be on the inner section or onthe outer section, so that the two sections are interchangeable, whichfacilitates the assembling of the frame in the wall opening. It is apparent that the sections may be quickly and easily removed forreplacement, if necessary, upon the withdrawal of the securing nails 16.The outer section is provided, adjacent its upper end, at approximatelythe plane of the upper surface of the refrigerator 23, with ahorizontally extending shelf portion 18, which is preferably formedcorrugated and which has its opposite ends angularly turned to formflanges 18, by which the shelf may be secured to the metallic frame. Asimilar shelf forming portion 19 is mounted on the inner section, theinner ends of these shelf sections overlapping, as at 20.

Wall bearing said opening.

this structure be used, inasmuch as the overlapping ends then serve tolock themselves together. A strap 21 is mounted on the angularly turnedportion 8, upon which is svvingably mounted adoor 22, so that there isprovided in the opening an auxiliary chamber, Which may be used for thestorage of different articles and access to Which is had from theinterior of the building, through the door 22.

V/hile I have illustrated and described the preferred form of structure,I; donot Wish to limit myself to the precise form of structure shown,but desire to avail myself of such variations and modifications as comeWithin the scope of the appended claims.

What I claim i I 1.. A metallic door frame of the class described,adapted for mounting in a door opening, and comprising a pair ofsections, eaclrhaving an inwardly projecting portion, one of theinwardly projecting port-ions being doubled upon itself, to provide areceptive channel for the inwardly projecting edgeof the ot ier portion,each of said portions having its outer end angularly turned at anincline to the inwardly promoting portion said an ularl turned ens beina ain 7 b V i o f1 angularly turned inwardly toward said 1n- Wardloroectm end portion and extend- J b l lng at right angles thereto, andadapted for engaging in close relation one face ofthe 2. A metallic doorframe of the class described, comprising a pair of metallic sections,each having a main body portion adapted for insertion into a dooropening formed in a Wall, the inner edges of said main body portionsbeing adapted for overlapping, the inner edges of one of said main bodyportions being doubled upon itself to provide a channel for thereception of the inner edge of the other section; an angularly turnedportion on the outer side of each of i said main body portions inclinedrelatively thereto, said angularly turned port-ion being doubled uponitself, to provide an engaging portion for engaging the faces of saidWall, said faces being normally under strain in engagement With saidall.

3. A door frame of the class described, comprising a pair of sections,each having a main body portion adapted for insertion from oppositesides of a Wall into an opening formed in said Wall, the outer ends ofeach of said sections being angularly turned to form, with saidmain bodyportion, a right angle triangle, said main body portion forming one ofthe legs of said triangle, and the other leg of said triangle being'inengagement With one face of said wall,'said main body portions beingadapted for insertion into approach relatively to each othersufficiently to place a strain on the hypotenuse of said trianglerandmeansfor securing said inwardly projecting ends in assembled relation. V

lutestimony whereof, I have signed the foregoing specification.
